WTB lil radio knobs, The the that control bass/mids/trebble Options

[urbandork]

I have the Radio/tape/cd Head unit in my celica. There are these three little knobs on the bottom right hand area of the unit that control bass/mids/trebble and when the two right ones are pulled out they contorl the balance and fade.

Im missing two of the plastic knobs that cover the metal part of the knob. If n e one has these plastic parts i wouldnt mind taking them off ur hands.

Its a small detail i know but some times its the small things that matters.

Thanks in advanced

I wonder if i can buy then from toyota lol jk. But if i can tell me or point me in the direction where i can lol
